Question:
Under which of the following condition, van der Waals' gas approaches ideal behaviour?
Under which of the following condition, van der Waals' gas approaches ideal behaviour?
Show Hint
Ideal behaviour is approached at high temperature and low pressure.
Updated On: Apr 20, 2026
- Extremely lower pressure
- Low temperature
- High pressure
- Low product of pV
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Real gases behave ideally when intermolecular forces are negligible.
Step 2: Detailed Explanation:
At extremely low pressure, volume is large, so molecular volume and intermolecular attractions become negligible. The van der Waals equation reduces to \(PV = RT\).
Step 3: Final Answer:
Extremely lower pressure.
